laterally by strong recurved costate margins which arc produced posterior- 

 ly nearly one-half the median length of the metanotum. Propodeum with 

 the basal area coarsely areolate, the basolateral areas excavated and sep- 

 arated from the posterior face by strong carinae ; sides shagreened; pos- 

 terior face more coarsely so, hexagonal, bounded laterally by carinae. pro- 

 foundly channeled in the middle. Abdomen impunctate above, trans- 

 versely lineolate, a little shining, tergite i strongly contracted apically 

 and 2 basally and apically; sternites similar to the tergites but with some 

 fine scattered punctures. Head broader than thorax, broader than long, 

 ej-es strongly converging below, clypeus about as high as broad at apex. 

 Thorax and abdomen rather slender. The first recurrent is received at 

 the apex of the first cubital cell, while the second is interstitial. 



The aedeagus very similar to that of A', licraldicus, X. Braunsi. and 

 iY. ruHpcdioidcs, agreeing with the latter on the gentle curve of the outer 

 side of the stipes and in the greater expansion of tlie sagittac in the 

 middle as contrasted with heraldicus and Braunsi. 



The eighth sternite has the margins straight on either side the apical 

 procesSj ruHpcdioidcs has them nearly so, while they are strongly .sinuate 

 in heraldicus and Braunsi. 



Length 5.5 mm., wing 4.5 mm.

By the descri])fi(in this species is similar to aherrans hnt 

 the strnctnre of the scutellum is different and the metanotum
